This paper presents a direct measurement between a macroscopic mass and two quantum standards in a single experiment. A current used to levitate a mass passes through a graphene quantum Hall standard, and the Josephson effect voltage is directly compared to the resulting quantum Hall effect voltage. Graphene quantum Hall arrays are used for resistance scaling, improving uncertainty and enabling higher current levels.
